TO WHOM IT MAY CONCERN:

Be it known that we, GEORGE Hoeven and ARTEMUSN. RADLEY, both of Richmond, Wayne county, Indiana, have invented a 'new and useful Hand-Spinning Machine; and we hereby declare the following to hc a full, clear, and exact description thereof, roference'being had to the accompanying drawings, making part of this specification.

rlhis is an improvement in the class of hand-spinning machines adapted for the simultaneous manufacture oi` a number ot' threads or yarns, and our invention comprises a provision for preserving a uniform pressure ot" l leiter-roller, with varying lengths and diameters of roving-spools; a provision whereby the act of depressing the clove sash becomes etiectual for the automatic delivery of the quantum of roving required for the ensuing stretch or draw; a provision whereby such automatic delivery is made adjustable in quantity' in inverse ratio to the desired draught; an automatic provision whereby the opening of the clove becomes effective to nip the Aroving-delivery cord and the closure of the clove to liberate said cord; a form of cloveiaws, adapted to securely nip the roving preparatory to drawing and twisting; an adjustable and automatic provision whereby the tallerily is alternately released and retracted by the descent and ascent o t' the clove-sash; an arrangement of spindledriving belt, whorls, und pressure pulleys, whereby an indeinito number of pulleys may be operated by a single belt; provisions for doubling and twisting in a. hand-spinning machine; a provision for reeling, tbc.

Figure lis a perspective view of a machine embodying our improvements, the sash havingr commenced its descent with its clove open, and the roving-delivery cord nipped. A portion of thc top .rail is, in this figure, shown broken away, so as to expose the spindles. l l. Figure 2 is a transverse section of the machine, with end views of the driving and counter-shafts.

The operative parts of our machine are supported in a frame, A, rectangular in its vhorizontal section, and somewhat high and broad for its width from front to back. The back of this frame may be vertical. Its front portion we prefer to lean slightly rearward, as shown. A front rail, B, and bacli rail, B', are crossed rectan gul-arly by two rails, C C, so attached to said rails BB as to be capable of boing set nearer together or furtherl l apart, and are provided near their rear ends with two bearings, D D', for the journals of a roving-delivery cylinder, E, 'lhese bearings, being slotted, are capable of approachment or separation, so as to admit cylinders of diierent lengths adapted to work with roving-spools of the diverse lengths and diameters employed by different cartlers. The cylinder E is scored e, oircumferentially, to receive and ho operated by the roving` delivery cord F. Attached adjustably to the rails lC C are two inclined arms, G G, which, in conjunction, with the cylinder E, form bearings for the roving-spool H, whose gudgeons, /t 7L', and periphery rest respectively upon said arms and the periphery of said cylinder. The arms G Gehould be set at such an inclination as to support the dofngroller I on the peripheries of the roving-spool H and delivery-cylinder E, as near the top of the latter as is practicable without rolling oli'. Extending from the bottom front rail L to the top front rail B, and parallel with the slightly inclined front posts J J of the frame, are two rods, K K', which serve as guides i to the clove-sash L M, whose front jaw, L, is provided with loops N enclosing said guides. Projecting rearward h from the jaw L are two brackets, O, to which the rear jaw M is hinged by moans of pivots P. Projecting downward and rearward from Vthe jaw L are eyelets, Q, which correspond in number to the spindles, and which serve to properly conduct the rovings oryarns thereto. The jaw L is, about its mid-width, excavated to receive and Y hold an India-rubber pad, R, which pad is traversed by the stem s of a loop, Spwhioh receives the roving. delivery cord F, and whose stem s aforesaid, being attached to the rear or movable jaw M, is drawn backward by the act of opening ofsaid jaw, sd as, at the proper moment, to automatically nip the cord F between said loop S and pad R, and thereby to cause the sash, in descending, to rotate the roving-delivery cylinder, so as to give out the proper quantum of roving for the ensuing dra-w Extending upward and rearward from the jaw L is a curved finger, T, which, as the sash approaches the top of its stroke, operates to retract the taller-wire, ir the manner presently explained. .Extending upward and forward from the jaw is a handle, U, by which to elevate and depress the sash. A spiral spring, V, extending from the lower part of the jaw L to the back of i thejaw M, act-S to close the said jaw M tightly against thejaw vL. A lip or ridge, m, on the jaw M, entering a groove, l, in the jaw L, or a series of corrugations on one jaw entering corresponding corrugations on the other jaw, enable the said jaws or clove to rmly gripe the rovings in the actot` closing, and thus eiectually prevent any slip of the yarn in the operation of drawing and twisting. Each bracket,.0, has/concentric with its pivot P, a groove, o, haring a jog or notch, o'. 'I his groove o receives a tongue, W, which is pivoted to and projects from the jaw' M. Depending from the frame is a tappet, X,'which,.u1resting the ascent of the tongue W as the sash nears the top of itss'troke, forces the jaw Mopenand the tongue into the jog o', which jog holds it and thejaw to said open position until released by the descent ofthe sash, bringing the tongue W in contact with a releasing or gaugepin, X', projecting .from the frame, whereupon the jaw M, being liberated, springs shut, and nips the rovings, releasing at the same instant the cord F, .as before stated, so as to stop for the time being the e'. delivery of the rovine. A series of holes, a, providedin the frame, enable the pin X to be shiftedup or down, so asto nip thcroving and to release the delivery-cord,earlier or later, in the downward stroke of tl'ie sash, according to the desired draught, thus adapting the machine for drawing and twisting either common' rolls or roving to any desired iin'cness or density, at the discretion of the operator, or for merely doubling andtwistingy yarn already spun. The spindles Y are journalled equidista'ntly in the top of the frame, with their points proljecting forward, and slightly downward, and reaching nearly vertically over the centre ofthe clove. The entire series of spindlc-whorls y are rotated simultaneously by means ofla round belt, Z, extending along their tops, and around the larger member 1 of a differential pulley, 1 2, which revolves onV a stationary counter-shaft or stud, Q5, and is driven by a belt, 3, extended from the driving-pulley 4 around the smaller member 2.'- The necessary impact and traction of the belt Z upon the whorls y is obtained bythe interposition of a suitable number of pressure-pulleys or idlers, 5, having their nadirs sulhcicntly below the zeniths of the whorls to accomplish that purpose. Provision for a slight-vertical adjustment of the plessurepulleys 5 may be mede by slottingl their bearings, and the application of a thumb-screw, 5'; but this adjustment once made is seldom required to be altered, and therefore to enable the belt to be readily strained or slackened without disturbing .the pressure-pulleys, the shaft 25 is made to occupy a slot, 26, in the frame, and being shifted vup or down therein at `discretion of the operator, is secured to any specific adjustment by means of a nut, 27. This pro;Y vision also facilitates thc cio'ssin.T of the belt'Z for doubling and twisting, as hereafter explained.. The fullerwirc 6 projects from a shaft, 7, jonrnalled in the frame, and is caused' to automatically assume a position near l the heels of the spindles by the stress of a spring, 8, attached to the end of an arm, 7*, which is so applied as to exert the great-est leverage on theshat't 7 when the wire isin said depressed position. The spring- 8 terminatos in a series of links, 9, either one of which being engaged over a hook, 10, on the frame, the automatic depression ofthe faller-wh-o is. made to'tahe place with any desired force. Depending rigidly from the fellerwire shaft is aspur, 11, which, when the said wire has been fully lifted orr retracted by the ascent ofthe curved linger T, before spoken of, engages on a shoulder, 12, of a bent spring, 13, attached to the frame, and thus locks or detains the fuller-wire to its upper position. The unlocking of the fuller-wire is effect-ed by the impingement of the bracket O, us the sash commences to ascend, against a trigger, 14, lconnected by a wire', 15, te a bell? crank, 16, which., slightly rctracting the bent spring 13, disengages the spur 11 therefrom, and releases the fuller-wire.

The spindles may bc run naked, after the manner of mule spinning, but wc prefer to use bobbins, which, when filled, may be slipped oi of thc spindles with their cops or breaches entire, 0r their contents may be drawn t off on to our reel, as will presently appear. The roving-delivery cord F is made continuons by means of hook and cyef, and being reve through the loop S is carried upward over a pulley, 17, attached to the front top rail by a hearing, which may be adjustable if desired, thence downward around a pulley, 18,whose bearing, 19, 'is slotted, and fixablc by a. screw, 20,011.1; or infor the proper tension of the cord. From the pulley 18 the cord'is. passed around the groove o in thc roving-delivery cylinder E, whence it returns again around thepulley 1'8. 'A

The sash L M is suspended by a cord, 2l, which, being carried over pulleys 22 and 23 hung in the top of the frame, terminates in a co'untcrbalnncc, 24. v The shaft 28 of the drive-pulley 4 journals, by its rear end, in a swivellcd box, 29, and by its' fore end in an open box, 30, to which it. is retained when4 desired by means of a hook, 3l. The said shaft terminates in front in a winch or crank, 38, which is, in conjunction with the handle of the sash, the prime mover of the entire drawing, spinning, and twisting operations. Projecting rectangularly from the front of the driving-pulley '4 is a series of pins or rundles, 32, which, in conjunction with said pulley, constitute e. reel employed in connection` with the doubling` and twisting arrangement, hereafter described, to wind off the worsted from the .bobbins A full hank having thus been wound off, can be readily removed from the r`eel upon temporarily lifting from its open bearing the crank end of the shaft 28. In order to be enabled to double and twist in the same machine, we provide, in rear of the roving-cylinders, ascries of studs, 33, carv 1 rying bobbins 34, two or more to cach upper spindle, and as many eyelets, 35, (of which only a. portion are t shown in drawing,) depending from a suitable rathe, 36, in rear of the frame. The object of these eyelets is to keep every individual thread apart from all the others and under proper tension, so as to prevent kinks and entanglement on their way to the eyelets Q. For doubling and twisting, we shift the gauge-pin X to anorilice, I f 37, `near the bottom of the frame, because for this purpose, no drawihg being needed, the clove is requiredv to. remain open during thecntirc descent ofthe sash.

To spin t'he rovings or continuous rolls, such'as are used in factories, take the spool iillcd with rovings and place it with its gudgeons resting;r on the inclined bearing-arms, and with its periphery resting on thatof the delivering cylinder, so that as thc-rovings are spun olf, the spool may gradually settle down on the cylinder. Then taking up the ends of the rovings, run off e. sufficient quantity to reach up through thesash to the points of the spindles or bobbins. Grasping then the handle of the sash, elevate the latter to the top of the frame, then bring the rovings through the eyelets at lthe bottom of the sash, and through the jaws ofthe same, being *i careful that all ofthe rovings are drawn up with equal tension from the spool below. The small roller or dolfer may nowbe placed'in the gorge of the roving-spool and delivery-cylinder, the inclined arms being raised or lowered so as to bring the dolfer as nearly as possible vertically over.` the cylinder. Then put the hobbies on the spindles, shoivng them as far back as possible, except that a sufficient` space must be left between the b'obbin and the frame to permit an unrestricted rotation of the spindles, and drawing the ends of the rovings under the now elevated fuller-wire secure them to their respective bobbins. i

To malte course yarn, more the gauge-pin down; to make fine yarn, move said pin up. The rovings being securely attached to the bobbins, the yet open sasl is to be depressed, letting the rovings pass through the open jaws, until the sash strik s the gaugthpin X on the upright, which action operates to release the cord F 'and to stop the delivery otn roving from the spool, and simultaneously therewith to nip allV the rovings at an equal distance below tho spindles. 'lhe operator now, with his right hand upon the winch or crank, twists a little in order to strengthen the rovings before continuing the downward motion of the sash, and then, while still revolving the winch, resumes said downward motion with gradually decreasing velocity, until the sash strikes the bottom rail, and then continues to twist until the yarn has attained the desired density. He then reverses the crank suiicieutly to clear the yarn from the points of the bebbins. He then commences to elevate the sash with his left hand, vkeeping hold ot' the crank with his right hand until the sash strikes the trigger and relieves the taller-wire. He thon, continuing to elevatethc sash with his left hand, slowly turns the crank forward with his right, and the yarn will he wound around the bobbins to form a breach or cop. On approaching the termination of its upward stroke, the curved finger on the top of the sash elevates the taller-wire, which, on its part, draws the yarn out to the end of the bobbin, and, becoming locked in the spring-catch or detent 13, sets the machine ready for the next draw.

To spin short rolls, such as are commonly used on the old spinning-wheels, the roving-delivery cord may be unhoolred and removed from the machine, and the rolls be spliced below` the sash as fast as they are spunup, and in most enses the gauge-pin should be shifted further up to secure the required draught.

'ilo double and twist, fill two ent-ire sets ot' bobbins, and remove the same from the spindles above te the studs below, and conducting the end of each yarn through its proper eyelet in the rathe, bring the said yarns l in pairs through their appropriate eyelets of sash, and through the jaws of the latter, and fasten each pair to its proper spindle,-then cross the belt Z, so us te give the spindles a reverse rotation, and shift the gauge-pin X to the bottom hole 3T, and operate the same as ins spinning. For tripling,, combine three yarns in the same For reeling, detach the belts and F, attach the end ofthe yarn or thread from. one or more spindles or bobbins to one of the rundles, 32, and turn the crank until a bank of the desired size is wound oit. Then slip the bank off of the rundles and let it hung on the main-shaft 2S, push back the hooi( 3l, elevate the front end of the said shaft clear of its hearing, and remove the bank. I
